Question

In which oxidation state, group 15 elements act as Lewis base?

Options

• + 5

• + 4

• - 3

• + 3

Answer 1

- 3

Explanation:

Due to the availability of a lone pair of electrons on the central atom, Group 15 elements behave as Lewis bases in the - 3 oxidation state. With an increase in the size of the center atom, the basic property of group 15 falls down the group.
